1. Product introduction:
The British TL laser biological sample discovery instrument has a super discovery function for biologically active substances such as blood stains, blood, sperm spots, sweat spots, urine, hair, dandruff, exfoliated cells, bone and tooth fragments; no treatment is required, and the biological The activity is non-destructive, which can fully guarantee the authenticity, integrity and biological activity of the original information of the material evidence. At the same time, it has the function of directly detecting gunshot residues, fibers, etc. and potential fingerprints.

Structure part:
The main unit is backpack type, which can walk directly. The equipment has a protective part box, real-time shockproof and waterproof protection. All parts do not need to be installed and disassembled.
1. Requirements for the control handle of the light source output end:
1) The control handle design of the light source output end is very suitable for the operator.
2) There is a screw hole for fixing the camera tripod at the bottom of the handle, which can fix the light-emitting handle, which is convenient for taking pictures.
3) The handle comes with a bracket, which can be directly matched with a 90-degree angle, as the fulcrum of the footprint lamp
2. Optical fiber:
    1) 3 meters;
    2) It is integrally connected with the host, no installation is required, and cannot be disassembled, which not only protects the host but also ensures the stability of the output power.
3) The optical fiber protection design is a triple protection design of iron sheet, rubber and fiber; it can protect the optical fiber from external force damage.
4) The optical fiber is retractable and can be retracted to the minimum state when not in use, which is convenient for protection
3. The device is powered by a built-in lithium battery, and the continuous output of green light can be more than 2 hours; the continuous use of blue light can be more than 10 hours.
4. Protection and portable design
    1) The host can be used in a fixed manner, or it can be carried in a backpack. It is equipped with a portable protective bag and a protective box to protect the laser host from time to time, shockproof and waterproof.
2) The equipment is integrally integrated with mobile wheels, with armrests and pull rods, which are convenient to carry and transport.
5. The equipment has a computer control system, digital and audio prompts. With start-up prompt sound, shutdown prompt sound, and battery signal recovery system, when the external temperature is too high, the standby time is too long, or the equipment is too high, the device itself has its own adjustment device to directly adjust the power to the available power. The battery displays the power, the alarm system when the remaining battery capacity is insufficient, and the alarm system when the environment is not suitable for laser light source equipment.
6. The output mode has two forms of digital and analog, which can be intuitively converted and displayed intuitively
7. With high-frequency power supply, it can be directly converted into high-frequency output when the battery power is weak, maintaining the observation effect
8. The device has a liquid crystal display, which can visually indicate the current output band by color, and can be selected by buttons. At the same time display the temperature, humidity, power, battery remaining capacity, time and other parameters in the current band
9. The device has an on-board power supply and can be charged directly in any car.
10. In order to facilitate the single police to carry and facilitate the on-site use, the overall weight of the equipment is less than 8 kg
